Rubus pascuus

L.H.Bailey

Rosaceae


The genus Rubus, (especially the blackberries, which are often loosely referred to as Rubus fruticosus agg.) presents some of the most difficult taxonomic problems. This is partly due to the frequency of polyploidy; also to the frequent occurrence of hybridization; and also due to apomixis, where minor differences between plants are preserved because seedlings are genetically identical to their parent. As a result, differences of opinion on the number of species to be recognized from a given region can vary tremendously (for example, a treatment by M. L. Fernald[

]. The stems only produce leaves, and do not flower, in their first year of growth; forming flowering branches in their second year and then dying after fruiting.
The plant is harvested from the wild for local use as a food. It is sometimes cultivated for its fruit in the USA with old cultivars such as 'The Topsy' and 'Tree Blackberry and more recent ones such as 'Naticope' (which is sometimes also referred to Rubus cuneifolius)[

Rubus pascuus is probably more widespread than indicated here. The species is most likely to be mistaken for Rubus bifrons, Rubus cuneifolius, or Rubus pensilvanicus. A notable aspect of Rubus pascuus is how vigorously armed it is, more so than most other Rubus species in the flora area[

Prick out the seedlings when they are large enough to handle and grow on in a cold frame. Plant them out into their permanent positions in late spring of the following year.
